Applicatio'ii mea November 24, 1919. serial No. 340,299,

To all eli/0m muy concern.'

Be it kno-wn that` I, JosnrH P. VOGEL, a citizen of the United States,and resident of Pittsburgh, in the county of Allegheny and State oi?Pennsylvania, have invented a new and useful Improvement in Pickingrlables; and do hereby declare the following` to be a full, clear, andexact description thereof.

ii) My invention relates to picking-tables for use in connection withmining operations where the coal or other mined product has certainimpurities which have to be removed before the coal is delivered intocars for shipment. l

The object of my invention is to provide a picking-table in which coalof different grades may be deposited on the same annular table, side byside and yet kept in l0 individual piles, and the refuse such as rockand bone picked therefrom from opposite sides and delivered by chutes tothe points desired, while the picked coal is automatically dischargedfrom the table, one grade going to one point and another grade toanother.

To these ends my invention comprises the novel features hereinafter setforth and claimed. p :io In the accompanying drawings, Fig. 1 is a planview of my improved picking-table;

Fig. 2 is a view partly in section of my improved table showing themannerof delivering the coal thereto and discharging it therefrom; andFig. 3 is an enlarged cross-section on theline 3 8 of Fig. 1.

In the drawing the numeral 2 designates a suitable platform on which aremounted pedestal bearings 3 within which are mounted the flangedidler-wheels 4.

The table 5 is annular in form, and secured to the bottom of said tableis the annular inverted rail 6 which rests upon the treads of theidler-wheels 4.Y Y

The table is divided into two compartments 7 and S by means of thepartit-ion 9, the compartment 7 being for nut coal and the compartment 8for lump. For convenience in picking it is desirable to have the nut andlump coal separated in this manner, for it is much easier to pick outthe bone and rock from coal of a certain grade than where coal ofdifferent grades are mixed together.

The inner and outer edges of the table are provided with the stationaryannular flanges 10.-

To provide a smooth surface'for the plow (hereinafter specificallyreferred to) to work on `in the nut compartment 7 a supple` mentalbottom-plate 11 is provided and which does away with the obstructionwhich would be offered by the flange of the angle 9 forming thepartition. i

To provide for the rotation of the table a rack 12 is secured to thelower side of the table and a clrivingpinion 13 meshes with said` rack,the connections between said pinion and the suitable motor being soregulated to drive the table at about 50 feet per minute at its centerline.

Plows 14 and 15 are provided, said plowsY being pivo-tally mounted so asto be swung into or out of position. The plow 14 is adapted to operateon the nut coal and is projected into the compartment 7 while the plow15 isadapted to act on the lump coal and is projected into thecompartment 8.

A chute 16 is located in position to receive the nut coal discharged bythe plow 14 and aloading boom 17 is provided to receive the lump coalfrom the chute 15a plowed by plowl from the compartment 8 of the table.1 Where it is desired to deliver the nut coal to the loading' boom 17for the lump coal, a fly gate 18 is provided in the nut chutev 16 and bv opening said the nut coal will be delivered by chute 18a onto theloading booml? to be delivered together with the lump coal at a commonpoint.

The chutes 19 and 20 deliver the lump and nut to their respectivecompartmentson the picking-table, the lump in the apparatus illustratedbeing delivered to the outside compartment and the nut to the insidecompartment. i

The pickers stand on'the inside and outside of the table and the refuseis picked and delivered into the chutes 21, said chutes communicatingwith a. common refuse hopperrnot shown.

By having a partition separating the lump from the nut coal on the tablethere is no liability of the same becoming mixed and consequently whenthe coal is discharged by the plows from the table the lump coal will goto the loading boom `17 while the nut coal will be discharged into thechute 16.

What I claim is: Y

1. An annular picking table, means for ce Y rotating saine7 means fordelivering different grades of coal to diierent Zones of said table, aloading boom, means for delivering coal from one of said zones to saidloading boom, means for delivering the coal 'from the other zone in adii'erent direction, and means for changing the means of direction ofthe coal from Said last named Zone #o said loading boom.

2. An annular picking table, means Jfor rotatingthe same7 means fordelivering' different grades of coal to different zones of said table, achute, means for discharging one grade of coal from one zone of saidtable to said chute, a loading boom to re- 15 ceive coal from saidchute, a second chute, means for discharging coal from another zone ofsaid table on to said second chute, and a gate in said second chutewhereby the material delivered to said second chute may be delivereddirectly on to said loading boom.

In testimony whereof I, the said JosnrH P. VOGEL, have hereunto set myhand.
